-WlCK-ADJUSTER FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 738,984, datedSeptember 15, 1903.

Application filed March 2, 1903. Serial No- 145,852. (No model.)

I0 all whom, it may concern.-

Be it known that I, BASIL F. CHESHIRE, a citizen of the United States,residing at St. Joseph, in the county of Buchanan and State of Missouri,have invented new and useful Improvements in WVick-Adj usters for Lamps,of which the following is a specification.

My invention relates to a wick raising and lowering device adapted fortubular Wicks of Argand burners as employed in kerosenelamps.

The object of my invention is to provide a convenient means for raisingand lowering the wick by rotation of a ring or collar surrounding aportion of the burner without moving the chimney-holder or the shell ofthe burner.

Referring now to the drawings, Figure 1 is a central vertical section ofa lamp-burner provided with my improved wick-adjuster, the innerwick-tube and the body of the lamp being broken away. Fig. 2 is asectional plan view of my invention, the lamp-body being omitted. Thesection-line of Fig. 2 corresponds to line a b of Fig. 1, and thesectionline of Fig. 1 corresponds to line cc of Fig. 2.

1 designates the upper portion of a lampbody.

2 is the burner-shell, or the lower portion thereof, which is insertedtightly or non-rotatably within the neck of the lamp-body.

3 is the outer wick-tube, to which the chimney-holder 4 is rigidlysecured.

5 is the inner wick-tube.

The upper edge of the shell 2 has an annular crimp 6 formed therein, bywhich a groove is formed just inside of the periphery of the shell.Resting in said groove is the bottom of an internally-threaded ring 7.Secured to said ring are a plurality of finger-pieces 8, by means ofwhich said ring may easily be rotated in either direction.

Three pairs of cars 9 are struck out from the outer wicktube at the sameheight as that of the threaded ring 7, and mounted rotatably betweeneach pair of ears 9 is a serrated Wick-wheel 12. The teeth of thesewheels are sunk into the wick 13 in the usual manner, and said Wheelsare engaged by the screwthreads of the ring 7, as shown.

The lower edge of the chimney-holder 4 is flanged downwardly, as at 14:,and said flange overlaps the upper edge of the threaded ring The wick israised or lowered by turning the ring 7 in one direction or the other.

I am aware that wick-raisers have been patented in which it is necessaryto rotate the chimney-holder or the burner-shell in order to adjustthewick, and such construction I do not claim as new.

Having now described my invention, what I claim as new, and desire tosecure by Lettors Patent of the United States, is-

1. A wick-adjuster for tubular wicks, comprising a non-rotatable outerWick-tube having a plurality of pairs of outwardly-projecting ears, aserrated wickwheel mounted between. each pair of said ears,achimney-holder secured to the outer wick-tube, and aninternally-threaded ring engaging the wick-wheels and rotatableindependently of the chimneyholder and of the burner-shell,substantially as described.

2. In a wick-adjuster for tubular Wicks, the

combination with a burner-shell, of an outer Wick-tube secured therein,a plurality of pairs of ears projecting outwardly from the outerwick-tube, a serrated wick-wheel mounted between each pair of said ears,an internallythreaded ring engaging said Wheels andsupported by theupper edge of said shell, and a chimney-holder secured to the outerWicktube and having a depending peripheral flange overlapping the upperedge of said ring, substantially as described.

3. A wick-adj uster for tubular wicks, comprising a burner-shell havingan annular groove within its upper edge, an internallythreaded ringseated within said groove, an outer wick-tube having a plurality ofpairs of outwardly-projecting ears, a serrated wickwheel mounted betweeneach pair of said ears, said wheels being engaged by the threads of saidring, and a non-rotatable chimney-holder provided with a dependingperipheral flange which embraces the upper edge-of said ring,substantially as described.

In testimony whereof I aflix my signature in the presence of twowitnesses.
